Abstract
A 36-year-old woman with rheumatoid arthritis is found to have a hematocrit (Hct) of 22% on a routine clinic visit. She has a history of blood transfusion 3 years ago with a negative antibody screen at that time. The patient is referred to the outpatient transfusion service for transfusion of two units of red blood cells (RBCs); a type and screen sample along with an order for the RBCs (ethylenediaminetetraacetic acid [EDTA] anticoagulant) is submitted to the blood bank.
